Using the LCD Module

The LCD module has built-in fonts and can be used to display text by sending appropriate

commands to the display controller, which is called HD44780. Detailed information for using the

display is available in its datasheet, which can be found on the manufacturer's web site, and from

the

Datasheet/LCD

folder on the

DE2-70 System CD-ROM

. A schematic diagram of the LCD

module showing connections to the Cyclone II FPGA is given in Figure 5.9. The associated pin

assignments appear in Table 5.6.
